The TUNZE Care Magnet is a glass pane cleaner which offers an ergonomic handle, and special plastic blades made of wear-resistant high performance plastic. It is significantly more compact than conventional algae magnets with a large cleaning surface, which blends into its surroundings unobtrusively, therefore enabling it to remain within the aquarium without disrupting the overall scenery. Scratches on the aquarium glass pane can be avoided by using this glass pane cleaner. With its small plastic blade the TUNZE Care Magnet can even be used on acrylic glass panes to a certain degree. The inner magnet is more than 3mm away from the aquarium glass pane, and thus prevents a jamming of the aquarium sand. Be careful when using partially magnetic sand (Hawaiian Black)! The two plastic blades remove the algae considerably better from the glass panes than a flat cleaning surface -almost as good as a sharp metal blade. The patented principle, which uses plastic blades with a different length, creates a varying application pressure, enabling the narrow blade to remove even tightly attached algae. With the wide blade, it is possible to perform a large-scale algae removal. The TUNZE Care Magnet doesn't distribute the algae within the aquarium as a green dust, it rather roles them up completely, and through this turns the algae film into actual food for the fish. Plastic blades with round edges enable a smooth transition to the next pane at the aquarium edges without damaging the silicone joints. The life of a blade is from several months up to approx. One year. The low flow resistance during the cleaning with a simultaneous high magnetic coupling, makes a separation of the magnet nearly impossible.
